v5.12.0→v5.17.1Warning
Some dependencies could not be looked up. Check the Dependency Dashboard for more information.
go-git has an Argument Injection via the URL field
CVE-2025-21613 / GHSA-v725-9546-7q7m
More information
Details
Impact
An argument injection vulnerability was discovered in
go-gitversions prior tov5.13.Successful exploitation of this vulnerability could allow an attacker to set arbitrary values to git-upload-pack flags. This only happens when the
filetransport protocol is being used, as that is the only protocol that shells out togitbinaries.Affected versions
Users running versions of
go-gitfromv4and above are recommended to upgrade tov5.13in order to mitigate this vulnerability.Workarounds
In cases where a bump to the latest version of
go-gitis not possible, we recommend users to enforce restrict validation rules for values passed in the URL field.Credit

go-git clients vulnerable to DoS via maliciously crafted Git server replies
CVE-2025-21614 / GHSA-r9px-m959-cxf4
More information
Details
Impact
A denial of service (DoS) vulnerability was discovered in go-git versions prior to
v5.13. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion ingo-gitclients.This is a
go-gitimplementation issue and does not affect the upstreamgitcli.Patches
Users running versions of
go-gitfromv4and above are recommended to upgrade tov5.13in order to mitigate this vulnerability.Workarounds
In cases where a bump to the latest version of
go-gitis not possible, we recommend limiting its use to only trust-worthy Git servers.Credit

go-git improperly verifies data integrity values for .idx and .pack files
CVE-2026-25934 / GHSA-37cx-329c-33x3
More information
Details
Impact
A vulnerability was discovered in
go-gitwhereby data integrity values for.packand.idxfiles were not properly verified. This resulted ingo-gitpotentially consuming corrupted files, which would likely result in unexpected errors such asobject not found.For context, clients fetch
packfilesfrom upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally bygo-git, or thegitcli, when new.packfiles are received and processed. The integrity checks for both files were not being verified correctly.Note that the lack of verification of the packfile checksum has no impact on the trust relationship between the client and server, which is enforced based on the protocol being used (e.g. TLS in the case of
https://or known hosts forssh://). In other words, the packfile checksum verification does not provide any security benefits when connecting to a malicious or compromised Git server.Patches
Users should upgrade to
v5.16.5, or the latestv6pseudo-version, in order to mitigate this vulnerability.Workarounds
In case updating to a fixed version of
go-gitis not possible, users can run git fsck from thegitcli to check for data corruption on a given repository.Credit

go-git missing validation decoding Index v4 files leads to panic
CVE-2026-33762 / GHSA-gm2x-2g9h-ccm8
More information
Details
Impact
go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing.This issue only affects Git index format version 4. Earlier formats (
go-gitsupports onlyv2andv3) are not vulnerable to this issue.An attacker able to supply a crafted
.git/indexfile can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition.Exploitation requires the ability to modify or inject a Git index file within the local repository in disk. This typically implies write access to the
.gitdirectory.Patches
Users should upgrade to
v5.17.1, or the latestv6pseudo-version, in order to mitigate this vulnerability.Credit

go-git: Maliciously crafted idx file can cause asymmetric memory consumption
CVE-2026-34165 / GHSA-jhf3-xxhw-2wpp
More information
Details
Impact
A vulnerability has been identified in which a maliciously crafted
.idxfile can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a Denial of Service (DoS) condition.Exploitation requires write access to the local repository's
.gitdirectory, it order to create or alter existing.idxfiles.Patches
Users should upgrade to
v5.17.1, or the latestv6pseudo-version, in order to mitigate this vulnerability.Credit
